Clinical Trial Summary

The objective of the study is to identify the relationship between patient position during surgery and time to confirmation of ureteral patency on cystoscopy.

Description:

Patients will be randomized to one of two arms: 0 degree supine position and 10-20 degree angle in reverse Trendelenburg. Our working hypothesis is that positioning a patient in 10-20 degree angle reverse Trendelenburg will result in shorter time to confirmation of bilateral ureteral patency and shorter total cystoscopy time, without a change in delayed diagnosis of ureteric injury.

Primary outcome: time to confirmation of bilateral ureteral patency Secondary outcome: total cystoscopy time, need for alternative modalities to aid in ureteral efflux visualization, delayed diagnosis of ureteric injury (evaluated 6 weeks postoperatively via chart review)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	time to confirmation of bilateral ureteral patency	time between initiation of cystoscopy and visualization of second ureteral jet in minutes	1 day
Secondary	total cystoscopy time	Total time of cystoscopy	1 day
Secondary	need for alternative modalities to aid in ureteral efflux visualization	After 10 minutes of no jet, it is okay for the surgeon to use alternative methods, including dextrose, sodium fluorescein, indigo carmine, IV diuretics, etc.	1 day
Secondary	delayed diagnosis of ureteric injury	evaluated 6 weeks postoperatively via chart review	6 weeks after surgery
